Question

Alena had 4 packs of gum with 6 pieces of gum in each pack. Hugh had 3 packs of gum with 5 pieces in each. Alena and Hugh have 19 pieces of gum left.

Which equation can we use to find p, end colour the number of pieces of gum Alena and Hugh chewed

Answer 1

`p = 4 * 6 + 3 * 5 - 19 = 20`

Explanation:

Number of packs available with Alena initially = 4

Number of gums in each pack = 6

Total number of gums initially present with Alena can be found by multiplying the number of packs with the number of packs.

i.e. number of gums initially present with Alena = 4
`*` 6 = 24

Number of packs available with Hugh initially = 3

Number of gums in each pack = 5

Total number of gums initially present with Hugh can be found by multiplying the number of packs with the number of packs.

i.e. number of gums initially present with Hugh = 3
`*` 5 = 15

Total number of gums present initially = 24 + 15 = 39

Number of gums left with Alena and Hugh = 19

The number of gums chewed can be found by subtracting the number of gums left with them from the number of gums initially present with them.

i.e. Number of gums chewed,
`p` = 39 - 19 = 20

The equation that can be used is:

`p = 4 * 6 + 3 * 5 - 19 = 20`
